Abstract The antioxidant N-(1, 3-dimethylbutyl)-N?-phenyl-p-phenylenediamine (6PPD) is
widely used to improve the durability of rubber. However, one of its transformation products …

N-(1, 3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) is a chemical added to tires
to prevent their oxidative degradation. 6PPD is highly reactive with ozone and oxygen …

Abstract Tire wear compounds N-(1, 3-dimethylbutyl)-N′-phenyl-p-phenylenediamine
(6PPD) and its derivative 6PPD-quinone have been considered as emerging pollutants and …

We here report chemical characteristics relevant to the fate and transport of the recently
discovered environmental toxicant 6PPD-quinone (2-((4-methylpentan-2-yl) amino)-5 …

To enhance tire durability, the antioxidant N-(1, 3-dimethylbutyl)-N′-phenyl-p-
phenylenediamine (6PPD) is used in rubber, but it converts into the toxic 6PPD quinone …

The antioxidant 6-PPD has been widely used to prevent cracking and thermal oxidative
degradation and to extend the service life of tire rubber. 6-PPD quinone (6-PPDQ) is formed …

p-Phenylenediamines (PPDs) have been extensively used in the rubber industry and found
to be pervasive in various environmental compartments for decades, while their …

The huge consumption of the tire rubber antioxidant N-(1, 3-dimethylbutyl)-N′-phenyl-p-
phenylenediamine (6PPD) has resulted in pervasive contamination in aquatic environments …

It has been reported that N-(1, 3-dimethylbutyl)-N′-phenyl-p-phenylenediamine-quinone
(6PPD-Q), a derivative of the tire antioxidant, N-(1, 3-dimethylbutyl)-N′-phenyl-p …
